Strange xml behaviour when opening the file.

Hi all,

I am experiencing a strange behaviour when i am trying to read an xml file.
I just want to print a message when the startofdocument is found.

the header file:

Code:

#ifndef KENTRIKO_H
#define KENTRIKO_H
#include <QtGui>
#include <QApplication> 
#include <QtCore> 
#include "ui_kentriko.h"
 
class kentriko : public QMainWindow
{
    Q_OBJECT
 
public:
    kentriko(QWidget *parent = 0);
    ~kentriko();
public slots:
void anigma_arxiou();
void diabase();
 
private:
    Ui::kentrikoClass ui;
    QXmlStreamReader ena;
};
 
#endif // KENTRIKO_H

the implementation

Code:

kentriko::kentriko(QWidget *parent)
    : QMainWindow(parent)
{
	ui.setupUi(this);
	connect(ui.anigma,SIGNAL(clicked()),this,SLOT(anigma_arxiou()));
	connect(ui.diabase,SIGNAL(clicked()),this,SLOT(diabase()));
}
 
kentriko::~kentriko()
{
 
}
void kentriko::anigma_arxiou(){
	QString fileName =
	             QFileDialog::getOpenFileName(this, tr("anigma arxiou"),
	                                          QDir::currentPath(),tr("arxia tipou  (*.xml)"));
	     if (fileName.isEmpty())
	         return;
	 QFile file(fileName);
	 ui.textBrowser->append(fileName);
	file.open(QFile::ReadOnly | QFile::Text);
	 ena.setDevice(&file);
}
 
void kentriko::diabase(){
ena.readNext();
if (ena.isStartDocument()){
	ui.textBrowser->append("start of document found");
};
//ena.readNext();
 
}

:

and the xml that I am trying to read:

Code:

<adbook>
 <contact email="kal@goteborg.se" phone="+46(0)31 123 4567" name="Kal" />
 <contact email="ada@goteborg.se" phone="+46(0)31 765 1234" name="Ada" />
</adbook>

when the diabase function is called my program crashes.

Any idea what might causing this?

Many thanks in advance.
